Tax Structure Overview

A single-member LLC in Colorado is typically treated as a 'disregarded entity' for federal tax purposes. This means your business income is reported on your personal tax return (Form 1040, Schedule C). You'll also be subject to self-employment taxes. We cover this in depth in our resource on starting a business in Colorado. However, you can elect to have your LLC taxed as an S-Corp for potential tax advantages. Colorado has a flat income tax rate, simplifying state tax calculations.
